I recently purchased a Jetboil Sol so as to be able to backpack in fire ban areas where my Zip could not be used. I tried the stove at home and immediately had trouble with it when hooked up to a coleman canister. I tried it on a partially used Brunton, still no luck, then a partially used MSR canister. The stove now worked and now seemed to also work on the Brunton and Coleman. I took a backpacking trip last week and at the last minute decided to use the Jetboil, I took the Coleman canister which was almost full. Oh what a pain it was!!! I would screw on the canister, hear the puff of gas as it screwed on then when I turned on the stove a puff of gas and it stopped. after much fiddling I found the only way I could get the stove to deliver gas to the burner was to screw it just a shade past the point where the gas escaped from the canister, nowhere near fully screwed on. The gas would then deliver erratically when I placed the pot on the stove, sometimes I could get it to burn full sometimes only at a simmer, the slightest touch to the pot and the burn rate would change significantly. There was never more than a puff of gas delivery if I screwed the stove fully onto the canister. I know I should use Jetboil canisters and as soon as I can find one I will try it. I thought it should work on all canisters as my Pocket Rocket did. Do I likely have a defective Sol or does it need Jetboil canisters exclusively? Its from REI so I am sure its no problem getting it replaced except REI is nearly 400 miles from home. Anyone have a similar problem.
